To change the wireless network password on Ubuntu, you can follow these steps:
- Click on the Network Manager icon in the top-right corner of the screen.
- Select "Wi-Fi Settings" from the drop-down menu.
- Click on the "Settings" button next to the wireless network you want to change the password for.
- In the "Wi-Fi Security" tab, change the "Password" field to the new password you want to use.
- Click the "Save" button to apply the changes.
If you are unable to access the Network Manager icon or you are using a version of Ubuntu without it, you can also change the wireless network password from the command line by following these steps:
- Open a terminal window by pressing Ctrl + Alt + T.
- Type the command nmcli device wifi list to see a list of available wireless networks.
- Find the network you want to change the password for and note the "SSID" and "BSSID" values.
- Type the command nmcli device wifi connect <SSID> password <new_password> bssid <BSSID> to connect to the network with the new password.
Make sure to replace
<BSSID> with the actual values from step 3.
